Hmmmm.... I'm on Win2kPro SP -2-, and VuePro has been very well behaved... Norton's AntiSpam broke part of the OS, so I'll have to strip her down to metal again, but I might get SP-3 and install it first, just to see if it has any effect on my stability... (I'd rather depend on hard and software firewalls, AV protection, and common sense experience to protect me from the Bad Things out on the Net; I've seen too many 'patches' that acted like a skin graft. One area of damage was fixed by peeling another....)
